I am also interested in what people think of this (so reviving this thread).

Lately I have been passing a Job in the constructor

class SubService(job: Job, ...) { ... }

and I use Job.invokeOnCompletion() to clean up any resource in it. I also like this for error propagation (the whole service fails if a subservice fails). If I don't want this behavior, I can just wrap the job with a SupervisorJob in the class.
